Forgive me if I'm just naive but I don't get the 'scary' part. Locks have always been 'advisory' and people who have wanted to circumvent them for both good and evil rate them by their 'time to disable'.

Hotel locks with hard keys had their issues as well, and were pretty trivially picked with simple tools. But the key is always that you need to bring the 'simple tools' which is to say that they aren't vulnerable in a way that someone who decides on the spur of the moment to enter the room can easily duplicate. They need the plug that fits the power cord, they need the software which does the JTAG wiggler etc etc.

So if it is 'scary' that people who are not affiliated with the hotel either as guests or as staff can, with pre-meditation, open a hotel room door without damage. Then you need to re-define scary. This has always been true, and will probably always be true by the nature of hotels and motels.
